Summary
These extremely compact DC-DC converters incorporate
all necessary input and output filtering, signalling and pro-
tection features which according to the latest industry
standards are required in the majority of applications. The
converters provide important advantages such as flexible
output power through primary current limitation, extremely
high efficiency, excellent reliability, very low ripple and RFI
noise levels, full input to output isolation, negligible inrush
current, soft start, overtemperature protection and input
over-/undervoltage lock-out. The converter inputs are pro-
tected against surges and transients occurring on the
source lines, covering a total input voltage range from
16 V DC up to 150 V DC with five different types.
The outputs are continuously open- and short-circuit proof.
LEDs at the front panel and an isolated output power good
option indicate the status of the power supply modules.
Voltage suppressor diodes protect the outputs against an
internally generated overvoltage.
Full system flexibility and n +1 redundant operating mode
are possible due to virtually unrestricted series or parallel
connection capabilities of all outputs. In parallel connection
of several units, current sharing option is provided by a sin-
gle wire interconnection.
As a modular power supply or as part of a distributed power
supply system, the low profile design significantly reduces
the necessary power supply volume without sacrificing high
reliability.
The units are designed as forward converters using planar
magnetics and control circuits in hybrid technology. The
switching frequency is fix at 307 kHz under normal operat-
ing conditions. Triple and quadruple output modules have
their voltage regulation of output 3 and 4 relying on the
close magnetic coupling of transformer and output conduc-
tor together with the circuit symmetry of their main outputs
2, respectively 1. Outputs with an equal output voltage can
either be series or parallel connected.
The fully enclosed, black coated aluminium case acts as
heat sink and RFI shield. It is particularly suitable for 19"
rack systems occupying 3U/4TE only, but can also be
chassis-mounted by means of four M3 screws. Connector
type is H15 and for single output modules H15 S2.
